We don’t need no stinkin’ badges!!

That was probably the last thing you said before you got the butt of a rifle to the back of the head from the guard at this abandoned Soviet base in former East Germany, I’d bet. Similarly, “I forgot it at home” would probably get you a thump to the old noggin as well, I imagine. I wonder if slipping a few rubles across the counter would get you in, though? Or maybe a bottle of Vodka?
